Assessment of deposit microstructure and all-weld and joint creep performance of the matching filler metal for the MARBN alloys

Substantial effort has been made in validating the MARBN alloys aiming to introduce new materials for the next-generation power plants. One of the essential tasks was to develop a welding filler metal for the component construction. The weld and the joint needed to provide adequate properties matching the base materials. Through two collaborative projects, IMPEL and IMPULSE, a matching composition filler metal, Chromet 933, was designed and...
